Cobalt3 has gotten hold of a very promising concept, but I feel the Pyramid V, even a latter model in the Pyramid line, is still a very buggy product. If Cobalt3 could lower the temperature requirements for the alarms, and make them a little more distinct and operational, it would already be a worthy product. I urge Cobalt3 not to give up on what they already have, but to look over the design of the product, and give it a little more testing.
